External non-maskable interrupt input
(Following sentence is added.)
P.2-9
If the CPUM register is accessed to make a transition to an operating
mode of SLEEP/HALT/STOP during execution of a program in external
memory, a branch instruction should not be located within the three
instructions immediately following the CPUM register access instruction.
Note :
P.2-13
Interrupts are prohibited and the bus is locked (occupied by the CPU)
when executing BSET or BCLR, however, if a BSET or BCLR
instruction is executed during program execution in external memory,
a bus authority release due to an external bus request may be interposed
between the data read and data write by the BSET or BCLR instruction.
If the atomic bus cycles (i.e. bus lock) of the BSET or BCLR instruction
need to be guaranteed in a system that uses multiple processors, either
of the following measures should be taken.
1. A program in which a BSET or BCLR instruction is executed should
be placed in internal memory.
2. Designate the bus authority request pin (BR) as a general-purpose
input port, and the bus authority release pin (BG) as a general-purpose
output port, for instance, so that bus requests cannot be accepted during
execution of a BSET or BCLR instruction.

(Following sentences are added to [Programming Cautions] of GETX.)
When "udf15 Dm, Dn" is operated, Dm is ignored.
The operations of "udf15 imm8, Dn", "udf15 imm16, Dn" and "udf15
imm32, Dn" are not assured. In addition, a system error interrupt does
not occur in these cases.
